Hexagon flange bolt is a fastener composed of hexagon head, flange face and screw, The hexagonal flange bolts produced by our company are made of titanium alloy, which are characterized by high strength, high thermal strength, good corrosion resistance, good low-temperature performance, high chemical activity, small thermal conductivity elasticity, etc. At the same time, its "ratio of support area to stress area" is greater than that of ordinary bolts, so this bolt can withstand higher preload and has good anti loosening performance, so it is widely used in automotive engines, heavy machinery and other products.
